INSTALLING THE STARPOINTER FINDERSCOPE
-
Loosen the two mounting screws near the bottom of the finderscope.
-
Choose the correct bracket for your telescope, and attach it to the base of the finder.
-
Tighten the screws to secure the bracket in place.
-
If your bracket is the dovetail type, loosen the setscrew on the telescope mounting bracket, slide the base of the finderscope into the bracket and tighten the setscrew.
If your bracket is the screw-on type, remove the two Phillips-head screws or thumb screws from the telescope. Place the finder over the screw holes or posts. Tighten the screws or thumb screws down to secure the finder in place. -
A clear plastic tab prevents the battery from discharging. Pull out the tab before using your finderscope.
* SOLAR WARNING! Never attempt to view the Sun through this finderscope or any telescope without a solar filter!
ALIGNING THE STARPOINTER FINDERSCOPE
The finderscope is one of the most important parts of your telescope. It helps you locate objects and center them in the eyepiece. The first time you assemble your telescope, you’ll need to align the finderscope with the telescope’s main optics. It’s best to do this during the day* using land-based targets.
* SOLAR WARNING! Never attempt to view the Sun through this finderscope or any telescope without a solar filter.
NOTE: Be sure to turn off the StarPointer finderscope when not in use to conserve battery power. New batteries can be purchased online or at watch/electronic stores.
-
Take the telescope outside during the day and turn on the finderscope using the power knob. Find an easily recognizable object, such as a streetlight, car license plate, or sign. The object should be as far away as possible but at least a quarter mile away.
-
Look through the telescope using your lowest power eyepiece. Move the telescope until your chosen object lies in the center of the view. If the image is blurry, turn the focus knob until it comes into sharp focus.
-
With the object precisely centered in the eyepiece, look through the finderscope’s optical window and locate the red dot.
-
Without moving the telescope , use the finderscope’s two adjustment knobs to move it around until the red dot appears over the object you are observing in the eyepiece.
-
It should not require realignment unless it is bumped or dropped. If you want to test the alignment, point the red dot at another land-based target. Then verify the object is in the center of the eyepiece’s field of view.
ACCESSING THE FINDERSCOPE BATTERY
The StarPointer finderscope uses a long-life 3V lithium battery (#CR2032), which is located on the StarPointer’s top surface. If you plan on not using your telescope for an extended period, we recommend removing the battery for storage. To remove or replace the battery, follow these instructions:
-
Using a Phillips-head screwdriver, loosen the battery cover screw and flip the cover open.
-
If you are replacing the battery, install the new one with the (+) terminal facing outward.
-
Place the cover back onto the finderscope and retighten the screw with the Phillips-head screwdriver.
NOTE: You will need a small Philips-head screwdriver to replace the StarPointer finderscope’s battery
SAFETY INSTRUCTIONS
